CASH REGISTER.

Application filed May 3, 1924, Serial N o. 710,956, and in Germany May 22, 1923.

This invention relates to cash registers and calculating machines and has more particularly reference to improvements in the totalizing counters of such machines.

The invention has for its primary object to provide a totalizing counter the movement of all parts of which substantially takes place withoutthe use of springs and the movable parts of which are locked against unintended movements in all of their positions.

Another object of the invention is to provide a totalizing counter which is of a very compact construction so that a plurality of counters may be inserted in one machine without any difiiculty.

The subject-matter of the invention therefore comprises novel means for the setting of the tens and the zero setting of the numeral drums.

lVith these and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims, and a preferred form of embodiment of which is here inaft-er described with reference to the drawings which accompany and form part of this specification.

Fig. 16 is a perspective view of the frames of the totalizing counters;

Fig. 17 is a sect-ion through the mechanism for moving the counters into and out of cooperative engagement;

Fig. 18'shows details of the amount setting mechanism.

The cash register illustrated in the drawings is provided with a plurality of totalizing counters which are adapted tobe selected by a hand lever for throwing them into the actuating members. The setting of the amount is likewise effected by means of hand levers. The amounts set are transferred to the totalizing counter thrown-in cooperative engagement by the operating mechanism of the machine through the intermediary of special toothed gearings.

Every totalizing counter is provided with a mechanism for setting the tens with which the setting operation which is divided into two phases, is performed by a step-like member which successively acts on the several points of the totalizing counter from the right to the left. This actuating member cooperates wit-h tens setting sleeve-s carried by a special shaft. The said sleeves are shifted endwise by the transition of a totalizing member from 0 to 9; a quarter of a revolution is imparted to them for performing the transferring of the tens and, during the zero setting of the numeral drums, they are moved together with the said shaft away from the totalizing members.

The zero setting of the numeral drums is effected through the intermediary of the stepped tens transfer member upon rotating the shaft of the totalizing counter by means of a key introduced into the machine. During this operation the tens transfer member is shifted axially and lugs which are fixed to the same, enter into the path of zero setting stops of the numeral drums. hen the tens transfer member is shifted axially, a plate provided with peep holes ill and usually hiding the numeral drums of the totalizing counter is adjusted in such a manner as to allow the amount registered by the totalizing counter to be read.

The mechanisms for throwing in and out the totalizing counters, for setting the amount .and bringing the latter to the totalizing counters are exactly the same as those described in applicants application Serial No. 691,484, filed February 8, 1924. These mechanisms will therefore be described only in as much as :it is necessary for the understanding of the lnvention.

Mounted for rocking motion on pivot pins 60, a between frame members A and A "(F-igs. land 16) are the frames B of the are rigidly connected with the totalizing wheels (Z4 which cooperate with a; rack H having atits upper end a toothed portion h which is in mesh with a differential wheel 7& which is freely rotatable on the main shaft P. Arranged for free rotation besides the differential wheel k is the amount setting lever h This leveris held in every set positionby a locking device h", it. The setting levers are rigidly connected with a single tooth h and a disk if. The latterpossesses a gliding surface 71 concentric with relation to the shaft P, and incontinuation of said surface a series of teeth It. As shown in Fig. 1 8, the gliding surface extends up to the upperflank of the single tooth h. Cooperating with the disk h and the differential wheel it? is a planet wheel h which is mounted. by a pin 29 on an arm 3)? rigidly connected to the shaft P. The

planet wheelpossesses a recess 71 lying in another recess h which lies in the plane of the single tooth ZLG. VVhen the recess a is in contact with the gliding surface, the tooth of the planetwheelh lies in a direc tion radial with respect to the shaft P. The above described device is provided for every denomination of the machine.

The sha ft P carries at its right-hand end a crank arm- 22 to which is pivoted a rocking rod 29*. The other end of the rod 32 is guided by a rod 72 which is mounted on the frame of the machine. The rod p shows a cam groove p which is engaged by a roll p of a toothed wheel 39 mounted on the frame. of'the machine. The toothed wheel p is in mesh with aftoothedwheel p to which the crank handle 32 is fixed,

is the shaft C of the the The operation of the differential mechanism is as follows: After the setting lever h has beenset to an amount, f. i. to the number 2, and the tooth it together with the single tooth it have thus been moved away from the tooth I7L13 by a distance of two pitch-units (Fig. 18), a revolution is imparted to the crank-p During thisopera planet wheehby its tooth h carries with it the differential wheel [L2 as long as it'is locked against separate rotation by its recess k and the gliding surface 7L8. As soon as the tooth 72. strikesfagainst the single tooth it the planet wheel h is forced to execute a rolling motion on the teeth h which areat rest. 'As a result thereof, the

differential wheel 7L2 comes to rest after it i has been carried along for a number of units (in this case 2 units) corresponding to the I During the return movement of the arm p the differential wheel [L215 set number.

again brought backto its position of rest.

The angle levers'are mounted on the pinsa Pro ectmg mto'the claw-shaped gaps r are pins T which are attached to'the-side walls b -of the totalizing counters. 7 is the selectinglever which is loosely supported on the shaft P (Fig. 1) and adapted to yertically shift a slide r in a guide of the frame of the machine. The slide 7- carries onpins 1 (shown in dotted lines in Fig. 17-) rockable fitting members 5 r which are adapted to be successively brought into the gaps r by shifting the slide 9*. The gap r is so large as to be filled by the fitting members r and the pins T. v

Transfer mechanism and zero resetting mechanism.

Lugs of the upper ledge b of the frame B of the totalizing counters swingingly support a frame E by means of pins 6 6 (see more particularly Fig. 16). A shaft F which is shiftable in the frame E, is locked against rotation by a pin 7' which is guided in a slot 6 of the frame E (Figs. 2, 3 and 16). Mounted for free rotation on the shaft F are tens setting sleeves G, one setting sleeve each being arranged between a pin 7' fixed to the shaft F and a flap of the frame E (Figs. 2, 3, 7). Every setting sleeve G consists of four parts rigidly connected with one another (see particularlyFig. 7) a circular disk 9 a single tooth g a locking member 9 having recesses g g g, g", 9 (Fig. and an end piece which is provided with an actuating piece 9. In the units section (Fig. 2, at

1 the right), there is provided a disk 9 inin mesh with the racks H. Every numeralv wheel D is provided at its left-hand side with a groove (Z which shows at a certain point a switch cl (Fig. 3). The pin 9 of the setting sleeve G is adapted to cooperate with this groove (F.

In order to provide for an easy operation, the angle which is formed by the switch (l and the edge of the groove, is made as acute In order to allow the actuating pin 9 to be rocked into the position indicated in Fig. 12 by dot and dash lines for the purpose to be hereinafter stated, the switch is made yieldable. The switch point (5 is fixed to a lever (Z mounted on a pin (5 in the numeral drum D and projecting with its upper end into a recess (Z of the bottom of the groove (Z A spring (1 tends to permanently press the upper end of the lever (Z toward the right (Fig. 12). Q If the ac tuating pin is swung into its horizontal position, the point (Z will give way toward the left while during the setting motion of the numeral drum D, which takes place in the direction of the arrow 2 of Fig. 12, the upper end of the lever (Z abuts against the right-hand limit of the. recess (Z when the sleeve (Z is a ratchet wheel (Z which is of the shape to be seen from Fig. 9. Its shallow broad recesses d cooperate with the disk 9 or with the cylindrical portion of the single-tooth disk 9 while the deeper narrow recesses (Z are adapted to be engaged by the single tooth g itself. The ratchet .wheel (Z carries on its right-hand side face a pin (Z and a substantially arc-shaped plate spring (Z with a bent-off end (Z the object of which spring will be explained hereinafter. The shaft C has rigidly fixed to its disks 0 the smooth peripheral surfaces of which are interrupted each by a single tooth 0 As is to be seen from Figs. 7 and 10, those single teeth 0 are arranged in stepped relation to each other, so that upon rotation of the shaft C the tens transfer sleeves G, the locking members of which cooperate with the disks 0 are actuated successively. Near the side wall 5 the shaft C carries a disk 0 which is provided with two switches 0 0 These switches are adapted to cooperate with the lower portion of the pin f and shift the same laterally together with the shaft F. The hub 0 (Fig. 2) of the disk 0 projects outwardly through the side wall 6 and has clutch teeth 0 at its right-hand end. All of the single tooth disks 0 and the switch disk 0 carry on one of their side faces zero set.- ting pins 0 which are adapted to be moved into the path of the pins (Z by imparting endwise shifting motion to the shaft C.

The journal pin a of the frame B is made to extend beyond the right-hand side of the bracket A It carries a cylindrical drum J which is rotatable but not shiftable. The drum shows on its peripheral surface a cam groove 2' (Fig. 2) and on its left-hand side face a cam groove 2' (Fig. 8), while its righthand end is offset and provided with slotlike notches F. A suitably shaped key may be introduced into those notches for the purpose of rotating the drum J. Projecting into the cam groove 1' is a stud 2" which is fixed to an intermediate member 71 This member 2' has a longitudinal groove (Fig. 4) which is engaged by an offset portion 0 of the shaft C (see also Fig. 2) in such a manner as to allow the shaft C and the intermediate member i to rotate but not to shift with relation to each other. As will be seen from the course of the cam groove 71 (Fig. 3), a rotation of the drum J will cause the pin i the intermediate member if" and the shaft C together with all parts carried by the same to be shifted to the left. Notwithstanding this endwise shifting movement, there may simultaneously take place a rotation of the shaft C around its geometrical axis and a rocking on the pins a a without the force-closed connection between the several parts being interrupted.

A pin a (Fig. 16) of the bracket A rotatably supports an angle lever K (Fig. 8).

The downwardly extending arm of this angle levercarries a pin lc which engages the cam groove 2'? of the drum J. The upper arm, which when seen. from the front iscranked toward the left-hand, possesses a cam slot 7& which is engaged by a pin 6 of the hand-end ofthe shaft C. They are held in their position by a portion a of the frame of the machine. The, pinionIM possesses on its'left sidea coupling'notch m which cooperates with the clutch teeth it is in mesh with a pinion m? (Fig. 15') which is freely rotatable. on thepin a and driven during the operationrof the machine by a rack m mounted for reciprocation in the frame of the machine. The rack m receives its reciprocatory movement by a grooved cam diSk,'similar to the disk B (Fig. 1) moved by the crank 19. V

jThe pinion N 2) possesses on its right-hand side a coupling'notch n which willrbe engaged by a pin 0 of the shaft C when same is shifted to the leit. The pinion N has eleven teeth and a free space 02 (Fig. 14:) where a tooth is omitted. It cooperates with" a gear wheel a whichis fixed to the drum J and which has only part of its rimprovided with teeth. When the mag chin-e is at rest, the pinion N 18 held in-lockedr position bythe free space n rbeing 1n engagement with the toothless rim portion a of the wheel a As the wheel 11, has eleven spaces of teethpthe pinion N will make one revolution at each revolution of the wheel m The front side of the totalizing counter is covered by a plate 0 (Figs. 9 and 11) which possesses peep holes 0 for the numeral drums. The, upper edge of the plate 0 is provided with rectangularly bent flaps 0 the enlarged ends 0 of which are adapted to cooperate with the recesses 9 and g of the setting sleeve Gr. Shiftably mounted in horizontal guides-of the frame B in rear of the plate 0. is anintermediate plate 0 his plate carries a slotted pin 0 (Figs. 2, 3 and 11) the slot of which is engaged by one of the disks 0? so'that the lateral position of the plate r0 is determined by the respective lateral position of the shaft C. Lugs 0 of the plate o which are directed toward the shaft C enter into the path of the ends (Z of the. springs (Z when the plate is shifted for the required distance to the left. Upon such shifting movement peep holes 0 of the plate 0 will register with the peep holes 0 of the plate Use as to allowthe inspection of the numeral drums D'which are, usually concealed. n V v The operation of the tens setting mechanism is as follows:

gagement withthe racks H (Fig. 5). The pin 6 of the frame E is in the lower portion of the groove k '(Fig. 8) and the frame E is in its lowered position. The lower end of the pin 7 of the shaft Fabuts right-hand side of the switch disk 0 this position of the shaft F, the pins 7" hold the tens setting sleeves G in their right limit position and the circular disks 9 of the sleeves G engage the broad recesses (Z of the ratchet wheels al so that the numeral drums D are locked against unintended The recesses g of the sleeves G are in engagement with the 'cylinorical' portion of the disks 0 (Fig. 10) thereby holding the' actuating pins 9 in elevated position'(Fig. 5); The stud i together with the shaft C are in the right-hand limit position (Fig. The zero setting pins 0 are outside the path of the pins (Z The shaft C is couplednwith the pinion M the through the means 0?, m while the coupling n 0 between the shaftC and the pinion N is released. At the beginningof the oper, V

ation of the machine a downward movement isimparted to the rack m by rotating the crank During this motion theshaftC together with the disks 0 is moved in counter-clockwise direction 1 0) through the intermediary of the pinions m M and the coupling m 0 Owing to their step-like arrangement the single teeth 0 successively act on the setting sleeves G from the left to the right,.the single teeth 0 engagingthe notches g so that the same will come into the position indicated by dot and dash lines in Fig. 10, the setting sleeves will execute a quarter of a revolution in clockwise direction and the actuating pins g will engage the grooves (Z of the numeral drums 1);, At the same. time the single tooth will come into the position indicated by dot and dash lines in ig. 9. All of the setting sleeves having been rotated in the described manner, the switch of of the disk 0 will strike against thelower portion of the pin f and shift the latter from the right- ,to the left-hand side of the switch disk 0 so that the shaft F together with the pins f isshifted to the left and the setting sleeves G are released by the pins f for being shifted to the left. The position reached by the shaft F after this period of movement is shown by Fig. 2. However. the setting sleeves G do .not take part in the shifting movement of the shaft since their pins 9 are held by the grooves 5Z The totalizing counter selected by the selecting lever r is now rocked in the described way about the pins a a from the positionaccording to Fig. 5 into'the position shown in Fig. 6. The gear wheelsd are thus caused to mesh with the racks H. The pin 6 of the swingingframe E simultaneously moves toward the right (Fig, 8)

lull

into that portion of the slot of the angle lever K which is situated at a higher level, the frame E being thereby rocked upwardly and the setting sleeves G lifted from the ratchet wheels (Z and the single tooth disks 0 The position of the frame B and the frame E after the said rocking mo ion is shown by the dot and dash lines in Fig. 8. The shape of the slot k is such that the ratchet wheels (Z are released only after the gear wheels (Z have entered into mesh with the racks H. As will be understood with reference to Fig. 6, the actuating pins 9* will remain in engagement with the groove (Z also in the elevated position of the frame E. The recesses g of the setting sleeves are engaged by the projections 0 of the plate 0 and the sleeves are thus locked against rotation.

The racks H are now shifted downwardly in accordance with the amount set by the setting mechanism of the machine and the racks, in turn, cause rotation of the gear wheels (Z and numeral drums D in the direction of the arrow :0 of Fig. 6. If, during this rotary motion, the number 9 is going to be replaced by the number 0 in the peep hole of a numeral drum, the switch (Z of the groove (Z -of the numeral drum contacts with the actuating pin 9 and displaces it together with the setting sleeve G to the left, so that the single tooth disk 9 will be caused to take its position above the ratchet wheel (Z of the next higher degree (Figs. 2 and 3, second setting sleeve from the right), while the actuating pin 9 will be moved to the left side of the edgeof the groove 6Z5. After the amount set in the setting mechanism of the machine has thus been transferred to the numeral drums, the frame B is returned by the operating mechanismof the machine into its position of rest (Fig. 5), the pin 6 entering the lower portion of the cam slot Z2 before the gear wheels (Z have come completely out of engagement with the racks H. The frame E is rocked into the initial position (Fig. 9) so that the setting sleeves Gr re-entcr into engagement with the disks 0 and the ratchet wheels (Z as in the position of rest of the machine. However, the recesses 9 instead of the recesses are now in contact with the disks 0 and the setting sleeves G which have been shifted to the left, have their single tooth disks 9 instead of their circular disks g in engagement with the ratchet wheels (Z The rack m 15) is now again moved upwardly whereby the shaft C is returned clockwise into its initial position and the single teeth 0 return the setting sleeves to the position shown in Fig. 5 by imparting to them successively from the right to the left a return rotation by a quarter of a revolution. Those of the setting sleeves which had been shifted to the left for the tens transfer, by their single tooth g rotate the ratchet wheel (Z of the next higher degree by one unit, while the setting sleeves G which have not been shifted, lock the corresponding ratchet wheels (Z against rotation by means of their circular disks The angular position of the several single teeth 0 with relation to one another is determined so that a tooth 0 will not come into engagement with its setting sleeve before the single tooth of the next lower degree has finished its operation. If therefore, during the rotation of the shaft G, a numeral drum D is turned by the operation of a setting sleeve from 9 to O, the switch rZ of this numeral drum will shift the corresponding actuating pin of the left neighboring setting sleeve G and the latter itself to the left so that, during the 1 immediately following operation of the setting sleeve by the corresponding single tooth disk 0 the numeral drum of the next higher degree will likewise be turned by one unit. In this way a universal tens transfer is attained.

lVhen all of the setting sleeves have reached the angular position according to Fig. 5, the continued rotation of the shaft C will cause the switch 0 to strike against the pin 7: and shift the same together with the shaft F again to the right. The lower end of the pin 7' takes its position on the right-hand side of swith disk 0 and is locked there. Those of the setting sleeves which had been shifted to the left, are reshifted to the right so that all parts of the device are returned to their initial positions.

The zero setting of the totalizing counter is effected by imparting one revolution to the drum J in the sense of the arrow 11 Fig. 8. This revolution may be executed by the intermediary of the operating mechanism of the machine or by means of a key inserted into the notches i of the drum J. At the beginning of the rotation, the stud 2'" together with the shaft C and its disks 0, are shifted to the left by the cam groove i so that the Zero setting pins 0 enter into the path of the pins (Z (see dot and dash position in Fig. 2). As the intermediate plate 0 is coupled by its pin 0 with one of the disks 0 it takes part in the shifting motion of the shaft C and therefore its lugs 0 are shifted to the left and caused to enter into the path of the ends (Z of the springs cl. The peep holes 0 of the plate 0 register with the peep holes 0 of the cover plate 0 and the amount contained in the totalizing counter may be read as long as the rotation of the drum J is not continued. If it is only intended to read the amount of the totalizing counter, the parts may be returned to their initial position by simply returning the drum'J after the reading has taken place. For the purpose of zero'setting'the rotation is continued. Upon shifting the shaft C to the left, its pin 0 engages the coupling notch 47, of the pinion N, the shaft C being therebycoupled with'the said pinnion while it is at the same time disengaged from the pinion M in as'much as the clutch teeth 6 are caused to disengage from the slot m of the pinion M. In the meantime, the pin 7& (Fig. 8) is moved by thecam groove 2' toward the pin a, whereby the angle lever K is caused to rock in counterclockwise direction and the frame E swung upwardly by the action of the slot k on the pin 6 The gear wheels (Z are thus released by the setting sleeves G the recesses g -of which receive the projections 0 so that the sleeves are locked against rotation. Up to this time, the toothless rim port-ion n of the wheel a (Fig. '14) had moved underneath the space a of the pinion N coupled to the shaft C so that the shaft C was held locked in its initial angular position. The teeth of the wheel a now enter into mesh with the pinion N and a full revolution is imparted to the shaft G in clockwise direction. According to-th'e position of the wheels of the totalizing counters the' zero setting pins c -will sooner or later strike against the pins (Z and carry these and the numeral drums D with them into the zero posit-ion. Shortly before the numeral drums reach their zero position, the ends 6 12 of the springs (Z come underneath the lugs 0 of the plate 0 and constitute rigid stops for the pins al (see dot and dash position of the spring in Fig. 9-), so that the numeral drums are prevented from turning beyond the zero position. The arrangement of resilient intermediate members (Z for the zero setting is necessary because the zero setting shaft Gmust make a complete revolution in being returned into its initial position in contradistinction to other zero setting devices with which only a revolution of the carrying shaft takes place.

After the shaft C has executed a complete revolution, the frame E is lowered by the intermediary of the cam groove 7?, pin 75 angle lever K, slot 76 and pin 6, the relative locking between the numeral drums D and the setting sleeves G, already described, being thus putagain into action. At the end of the rotation of the drum J the cam groove 71 (Fig. 3), owing to its particular course. will return the stud i and the shaft G into the right-hand initial position The zero setting pins 0 retire out of the path of the pins'd and the lugs 0 of the plate 0* release the springs (Z The latter spring back into the position indicated by full lines in Fig. 9. During the movement of the shaft to the right the coupling between the shaft C and pinion N is interrupted, while the Thus, all parts of the device are returned into their initial position andthe numeral drums into their zero position.
